Give it a try

1. To add items to your Carousel, you'll need to add a hidden sub-section called Carousel (case sensitive) directly beneath the section where you'd like the Carousel to appear (it's a hidden repository folder and so the 'Show in navigation' option needs to be unticked).

2. Add a second hidden sub-section below your new Carousel sub-section. You can name this sub-section as you wish. In my example I've called the sub-section: Flowers.
